HydraFabber - after [[HydraRaptor]] - is a portable, multi-headed CNC fabrication machine that can do 3D printing, circuit milling, and laser cutting. It is intended to be a portable machine that can be brought to [[OSE Design Sprint]]s for prototyping. During the sprints, we design machines in [[Sketchup]], and then prototype them by printing out modular parts with a [[3d_printer|3D printer]] and [[Laser_cutter|laser cutter]]. The laser cutter cuts out flat sheets that are folded to make 3D beams and other parts, and these beams form 3D frames and other 3D parts. Then the [[CNC_Machine|circuit mill]] functionality can be used to prototype [[Circuit_boards|circuit boards]], such as controllers for automated machines.

*Please coordinate between [[John Log]], [[Leo Log]], [[Tim Boyd]], and [[Nate Log]] - all work related to [[HydraFabber]].

=Specifications=

==Functional Spec==

* 200x200x120mm mininimum build volume
* Quick change heads with accurate repeatable alignment
* Complete system includes robust carry case
* At most 10 minutes for a competent user to set up or prepare for travel

* Printer
** One material at a time
** heated bed to at least 140C
** reliable extruder
** hot end to at least 245C
** Glass print surface for flatness
*** Optional tape over glass for ABS adhesion
** Fan to cool print
** at least 60mm/s practical print speed (more is better)

* Laser
** 1.5W laser cutter diode

* Circuit mill
** depth of cut control relative to surface of PCB
** easy tool change
** effective quick change PCB holddown

* Folds up into a portable suitcase so it can be brought to design sprints and other events

===Functional Spec Questions===
'''General Comment: study of open source industry standards is our best bet. It appears the 3D printer part is all go. Shapeoko has sold 1500 of their routers - so let's assume they work well enough. Search for laser diode paper cutters on the web. Combine RepRap, Shapeoko - and come up with a design. I could foresee that the Router Module is just 2 reinforcement plates for the sides of the machine to provide rigidity. Perhaps use Shapeoko as base, add a 3D printer head or laser diode head to convert to the other 2 functions? Then we have structure all worked out. Does Shapeoko appear to get us the right accuracy?'''

* Is 1.5w optimum? '''See discussion at [[SLS_Wax_Printer]]. Requirement is anything that cuts paper.'''
* What wavelength? '''That which cuts paper, may have to work with black paper'''
* What laser radiation safety measures (1.5w is plenty to blind)? '''Good question. Let's research industry standards'''
* Fixed laser + moving optics or moving laser? '''Replacement for extruder head on the triple machine'''
* What feed rates would be ideal? '''Need to look at specs of laser diode or other projects'''
* How accurate do we need to be for circuit milling?'''Same performance as Shapeoko'''
* What is our target track pitch? '''What is this'''
** Are we aiming for through hole or SMT? If SMT, then how small (just SOICs or QFNs and BGAs)? '''Same as Shapeoko'''
* Is a Dremel-type spindle good enough? '''Appears so'''
** Noise? '''What kind of noise?'''
** Speed (RPM)? '''5,000 - 35,000'''
** Accuracy (TIR)?
** Mass - is it too heavy?
** Size - is it too big? '''No.'''
* Are there any reasonable off the shelf alternatives to the dremmel? '''Don't know. First prototype with dremel appears sound. Based on Shapeoko.'''
* How hard/expensive would it be to make a good small open source spindle? '''I wouldn't worry about it in the first iteration.'''
* What feed rates would be ideal? '''See Shapeoko'''
* What cutting forces are we going to get? '''I would say 2 lbs of force'''
* How do we hold down the PCB? '''Paper Clamps in first version?'''
* Will the dust from the PCB milling interfere with the 3D printing? '''We will have to get data on that.'''

== Quick Route to Functional Prototype ==

Almost any RepRap will fulfil the printer part of the functional spec. The need for quick-change heads without recalibration requires a new head mount that will position the head very repeatably each time it's mounted. A kinematic mount is under development for this purpose.

The more rigid RepRap the better. A Mendel90, MendelMax, ORD Bot, or TAZ would be particularly suitable.

Went to the hangout. I uploaded the True Fans Platform to some webspace so we could get a better look at it. It turns out that there are a few issues with it but the version on Github may be out of date. The original designer may have already fixed these issues (thumbnails in particular).

Soap nuts are an envirionmentally sensisitve and natural laundry detergent. A full article on Soapnuts can be found on Wikipedia at:

[http://en.wikipedia.org/wiki/Sapindus Soapnuts]

Some of the basic facts of soapnuts are:

* Have been grown and used for washing for thousands of years in India.
* Can be grown between 60 and 75 degrees F.
* Can be used for washing clothes, whipped for shaving, handwash, shower foam etc.
* Totally natural and accessible
* Excess crops can be sold
